either in a lateral or a vertical direction, and

at the same time to hold the end of the beam measurably rigid.

The nature `of the invention consists of a coupling for connecting theplow-beam to the4 axle of the carriage to which it is attached, whichcoupling consists of two metallic straps, fastened by bolts,respectively, to the top and bottom ofthe plow-beam, with a swivel-piececonnected to the front ends of the said straps by means of a verticalbolt passing through the said straps and swivelpiece, so as to allow thelatter a rotating movement on its assembling-bolt, for the purpose of alateral adjustment. The swivel-piece has serrations on its back edge, bymeans of which a couplinglink is adj usted and attached to it atdili'erent elevations, as required, and to the front end of thiscoupling-link is attached a tubular axle, so as to have as much verticalmotion about this connection as required.

These couplings are adaptable to any form of plows, but are especiallydesirable for use on cultivator-plows', where two plows of any form areworked together, the construction ofthe couplings permitting the plowsto be easily set at any required distance apart.

The invention Will be readily understood by reference to theaccompanying drawings, of which- Figure I is a side elevation of aportion of the end of one plow-beam, with the improved coupling attachedto it. Fig. 1I is a plan of the same. Fig. III is a longitudinalsectional elevation of the coupling and its attachments. Fig. IV is aplan of the connectinglink.

The plow-beam A has two metallic straps, B B', secured to its front endby means of the through-bolts a. The strap B is placed on top of theplow-beam, and the strap B on the bottom of the said beam, so that thedistance between these plates will be equal to the vertical depth of theplow-beam. Between the front ends of these straps, and titting in snuglybetween them, will be placed the swivel-piece C, through the verticalaxis of which, and through the ends of the straps B B', the bolt a willpass, so as to assemble these parts together, and as the said bolt a isround on the part of it which passes through the piece C, the saidswivel-piece will be free to turn laterally on this bolt, for thepurpose of lateral adjustment of the parts while in use, as will berequired when the plow or ploWs pass over uneven surfaces. The back faceof the swivel-piece has several notches, c, at different heights, eachof which notches is a segment of a circle, fitted to the peripheryr ofthe lateral assembling-bolt c. The connecting-link D, at its rear end,is fitted to embrace the swivel (l, and is attached thereto by means ofthe transverse bolt c. In assembling these parts together the bolt c isplaced in either of the notches o, as desired, so as to make the plowrun deep or shallowin the usual manner. The front end of the link D isattached to the tubular piece E by means of the clamping-strap F thatembraces the said tubular piece, and is secured in place by the nuts f fthat screw down on top ofthe link D, the two ends of the strap F passingup through the said link, so as to receive the nuts above the top faceof the same. The tube E is made to surround the rod Gr that forms theaxle of the carriage, and this tube is allowed a rotating motion on thesaid axle, for the purpose of permitting a free vertical adjustment ofthe parts While in use, so as to accommodate the movement of the plowsin passing over the asperities of the ground.

When two or more plows are used, these couplings are decidedlyadvantageous, as the plows can so readily be set at any requireddistance apart by` simply loosening the nuts axle-,piece E 'by means ofthe screw-strap vF, Jj', and moving thecoupling -to the position asdescribeda'nd setforth.
